Every team on SportSignals has a number beside its name. That number is the SportSignals Rating, or SSR for short. It tells you, at a glance, how strong a team is relative to others in their league.
This page explains what the number means, how it is calculated, what the different variants represent, and how you can use it to find value in the betting markets.
What the Rating Tells You
The SportSignals Rating is a measure of team strength based purely on match results. Every team starts at 1500. Winning moves the number up. Losing moves it down. The amount it moves depends on who you beat or lost to.
Beat a team rated much higher than you and your rating jumps significantly. Lose to a team rated well below you and it drops hard. Beat a team at a similar level and the change is modest. This means the rating naturally reflects quality of opposition, not just results in isolation.
After processing three seasons of results across seven leagues, the numbers settle into a reliable picture of each team's strength. The top sides in each league typically sit between 1650 and 1800. Mid-table sides hover around 1450 to 1550. Struggling teams drop below 1400.
Here is a rough guide:
| Rating range | What it means |
|---|---|
| 1700+ | Among the best in the league. Consistently beats strong opposition. |
| 1600 to 1699 | Strong side. Regularly competing at the top end. |
| 1500 to 1599 | Mid-table quality. Competitive but inconsistent against top sides. |
| 1400 to 1499 | Below average. Struggles against the better teams. |
| Below 1400 | Bottom of the table. Likely to lose more than they win. |
How the Calculation Works
After every match, the system runs a straightforward process.
First, it works out what "should" have happened based on the two teams' ratings. If Arsenal are rated 1700 and Brentford are rated 1480, the system expects Arsenal to win. The bigger the gap, the higher the expectation.
Then it compares what actually happened to that expectation. If Arsenal win as expected, both teams' ratings change by a small amount. If Brentford pull off the upset, the adjustment is much larger because the result was unexpected.
The formula uses a sensitivity setting (called the K-factor) that controls how much a single result matters. We use K=32 for the main rating, which balances responsiveness to new results against stability. A single match can move a rating by roughly 5 to 25 points depending on the result and the opponent.
Three Seasons of Data {#history}
The rating is not based on just this season. It processes results going back three full seasons across all seven leagues: Premier League, La Liga, Bundesliga, Serie A, Ligue 1, Eredivisie, and the EFL Championship.
That is roughly 8,800 matches. By the time the system reaches the current season, every team that has been active in these leagues has a well-settled rating built on dozens of matches against varied opposition.
This depth means the ratings are not guesswork. A team rated 1650 has earned that number through consistent performance over an extended period.
How Seasons Are Handled {#seasons}
Football teams change between seasons. Players leave, new ones arrive, managers come and go. A team that finished strongly in May might be a different proposition by August.
To handle this, the system applies a simple adjustment at the start of each new season. Every team's rating is pulled back one-third of the way toward 1500 (the average). So a team that finished at 1720 would start the new season at roughly 1647. A team that finished at 1340 would start at roughly 1393.
This does two things. It acknowledges uncertainty about how good a team will be with their new squad. And it prevents extreme ratings from becoming permanently locked in. Teams that are genuinely strong quickly build their rating back up through early-season results.
Promoted and relegated teams get additional adjustments. A team promoted from the Championship to the Premier League carries their Championship rating forward with a small downward adjustment (reflecting the step up in quality), then the seasonal regression is applied on top. A newly promoted team with no rating history at all starts at 1400, slightly below average.
The Rating Variants {#variants}
The main SSR measures overall strength. But for betting, you often need to know something more specific. Can this team score? Do they keep clean sheets? Are their matches typically high-scoring?
That is why the system calculates several specialised variants alongside the main rating.
Attack {#attack}
The Attack rating measures how consistently a team scores goals. After each match, the system treats scoring 2+ goals as a "win", scoring 1 as a "draw", and blanking as a "loss", then adjusts the Attack rating accordingly.
A team with a high Attack rating regularly finds the net. A team with a low Attack rating frequently fails to score. This is useful for backing a team to score, or for identifying opponents likely to concede.
Defence {#defence}
The Defence rating measures how reliably a team prevents goals. A clean sheet counts as a "win". Conceding exactly 1 goal is a "draw". Conceding 2 or more is a "loss".
Teams with high Defence ratings are hard to break down. Teams with low Defence ratings leak goals. Combined with the Attack rating of the opposition, you get a clear picture of whether goals are likely in a specific match.
Momentum {#momentum}
Momentum works the same as the main SSR but uses a much higher sensitivity setting (K=64) and only considers the last 10 matches. This makes it highly reactive to current form.
A team might have a strong main SSR (say 1650) but a weak Momentum rating (say 1420) if they have hit a bad patch recently. The reverse is also true: a mid-table team on a winning run will have Momentum well above their main rating.
Comparing a team's Momentum to their main SSR instantly tells you whether they are over-performing or under-performing relative to their season-long quality.
BTTS Index {#btts-index}
The BTTS Index measures how often both teams score when this team plays. After each match: if both teams scored, it counts as a "win" for the BTTS Index. If one or both sides blanked, it counts as a "loss".
A high BTTS Index means the team is regularly involved in open, end-to-end matches where both sides find the net. A low BTTS Index means their games tend to see one side shut out.
This is directly useful for the Both Teams to Score market. When two teams with high BTTS Indexes meet, the probability of both scoring is elevated.
Goals Index {#goals-index}
The Goals Index tracks how often a team is involved in high-scoring matches. There are two versions:
Goals Index (Over 2.5) treats a match with 3+ total goals as a "win" and 0-2 goals as a "loss". A team with a high Over 2.5 Goals Index plays in matches that regularly produce three or more goals.
Goals Index (Over 1.5) uses the same logic but with a lower threshold: 2+ goals is a "win", 0-1 goals is a "loss". This is useful for the Over 1.5 market, which is popular in accumulators.
Using SSR for Betting {#betting}
The rating system is a tool, not a crystal ball. Here is how to get the most out of it.
Reading the rating gap {#reading-the-gap}
The single most useful number is the gap between two teams' main ratings. It tells you the degree of mismatch.
| Gap | What it suggests |
|---|---|
| 0 to 50 | Very tight. Genuine coin-flip territory. Look at form and home advantage. |
| 50 to 100 | Slight favourite. The higher-rated team wins more often than not, but upsets are common. |
| 100 to 200 | Clear favourite. The higher-rated team should win the majority of these. |
| 200+ | Major mismatch. Upsets here are rare and usually headline news. |
When the bookmaker odds imply a tight match but the SSR gap says otherwise (or vice versa), that discrepancy is worth investigating. It does not mean the SSR is always right, but it highlights where the market might be mispricing the fixture.
Combining with market-specific ratings
For the BTTS market, look at both teams' BTTS Index values. If both are above 1550, the probability of both teams scoring is meaningfully higher than average.
For Over/Under goals markets, check the Goals Index. Two teams with high Over 2.5 Goals Index values facing each other suggests a high-scoring match. Two teams with low values suggests a tighter, lower-scoring affair.
For match result bets, the main SSR and Momentum ratings together give you both the long-term quality picture and the current form picture. A team with strong SSR but weak Momentum might be worth opposing in the short term. A team with weak SSR but strong Momentum might be worth backing before the market catches up.
Cross-referencing with odds
The SSR is most valuable when it disagrees with the odds. If the SSR gap says Team A is a clear favourite (150-point gap) but the bookmakers have Team B as slight favourites, something interesting is going on. Maybe there is an injury you have not accounted for. Maybe the bookmakers are reacting to recent results that Momentum already captures. Either way, it is worth digging into.
The flip side: when the SSR agrees with the odds, the match is probably priced fairly and there is less edge to find.
What the Rating Does Not Tell You {#limitations}
The SSR is powerful but it has limits, and being honest about those limits is important.
It does not account for injuries. If a team's best player is injured, their SSR does not drop until results start suffering. Check team news alongside the ratings.
It does not account for motivation. End-of-season dead rubbers, cup rotation, teams already safe from relegation. These factors affect performance but the SSR does not capture them.
It is within-league only. A rating of 1650 in the Premier League is not directly comparable to 1650 in La Liga. The quality of opposition is different. Within a league, comparisons are reliable. Across leagues, treat the ratings as relative indicators only.
It reacts to results, not performances. A team might deserve to win based on expected goals but lose 1-0 to a deflected shot. The SSR adjusts based on the actual result, not the underlying performance. Over a large number of matches this evens out, but in the short term, lucky or unlucky results can distort the picture. That is partly what Momentum is for: it captures short-term swings whether or not they are "deserved".
It is one input, not the whole answer. The best bettors combine multiple signals. SSR, odds movements, xG data, injury reports, tactical context. No single number tells the full story.
Where You Will See SSR Across SportSignals {#where}
The rating appears throughout the site wherever it adds useful context:
Prediction pages show both teams' SSR in the header, the gap between them, and market-specific ratings (BTTS Index, Goals Index, Defence, Attack) alongside the odds comparison. This gives you a proprietary signal for each market to cross-reference with what the bookmakers are offering.
Team pages display the full set of ratings for that team: main SSR, Attack, Defence, Momentum, BTTS Index, and Goals Index. You can see at a glance where a team is strong and where they are weak.
League tables have a Ratings view that ranks teams by SSR instead of points. This often tells a different story from the actual table. A team sitting 6th on points but 3rd by SSR might be undervalued by the market.
The comparison tool puts two teams side by side with all their ratings, form, and head-to-head record. It is the quickest way to size up a specific fixture.
Fixture cards on the predictions hub show the rating gap as a compact badge, so you can immediately spot the most lopsided upcoming matches.
Wherever you see a rating number, you can hover (or tap on mobile) the small info icon beside it to get a quick explanation of what that specific rating measures.

Frequently Asked Questions
What is a good SportSignals Rating? The average team sits at 1500. Anything above 1600 is strong, above 1700 is among the best in the league. The very top teams in the Premier League and La Liga typically sit between 1700 and 1800. Below 1400 usually indicates a team in the bottom quarter of their league.
How often is the SportSignals Rating updated? Ratings update automatically after every completed match, typically within a few hours of the final whistle. The system processes new results throughout each matchday.
Can I compare teams from different leagues? Ratings are calculated within each league, so a 1650 in the Premier League is not directly comparable to a 1650 in La Liga. The quality of opposition each team faces is different. For cross-league comparisons, treat the ratings as relative indicators within their own league.
What is the BTTS Index? The BTTS Index measures how often a team is involved in matches where both sides score. A high BTTS Index means the team's games frequently see goals at both ends, which is valuable information for the Both Teams to Score betting market.
How accurate is the SportSignals Rating for predicting match results? The rating system correctly identifies the stronger team in around 65-70% of matches where there is a clear rating gap (100+ points). It is one tool among several and works best when combined with other data like form, injuries, and market odds.
What happens to ratings between seasons? At the start of each new season, every team's rating is pulled back one-third of the way toward the 1500 average. This accounts for squad changes, new signings, and managerial shifts. Teams that are genuinely strong quickly re-establish their rating through early results.
How far back does the rating history go? The SportSignals Rating is built from three full seasons of match results across all seven leagues we cover. That is roughly 8,800 matches, giving every team a well-settled rating based on extensive data.
